Mandible X-Ray
A mandible X-ray, often performed as a panoramic radiograph (orthopantomogram or OPG), provides a comprehensive, two-dimensional view of the lower jaw and surrounding structures. The resulting image displays the entire mandibular bone, extending from one temporomandibular joint (TMJ) to the other, curved into a flat plane.
Key anatomical features visible in the image include:
- The Mandibular Body and Ramus: The dense, curved horizontal bone that holds the lower teeth, and the vertical segments (rami) that extend upwards toward the ears.
- Dentition: A complete view of both the upper (maxillary) and lower (mandibular) teeth, including the roots, crowns, and any unerupted or impacted third molars (wisdom teeth).
- Condylar and Coronoid Processes: The bony projections at the top of the ramus that form the jaw joint and anchor major chewing muscles.
- Surrounding Structures: Portions of the maxilla (upper jaw), the nasal cavity, and the maxillary sinuses positioned directly above the upper teeth.
In a clinical setting, this imaging is essential for diagnosing mandibular fractures, tracking dental development, evaluating impacted teeth, and identifying bone cysts, tumors, or infections.
